I. I w I aiif'inlct apertures 11 which may be controlled by a suitable valve structure 11bif desired which may be operated to cover or uncover the air inlet openings 11a to the desired extent and thereby regulate the amount ofair drawn into the distributing chamber 11 through" which the enriched vapors are carried to the engine or other consuming apparatus.

-The operation of this device -is substantially as follows: Power beingTt-ransmitted to the shaft 6 through any .suitable connection, the piston 3 is then .reciprocatedin' the cylin'de'r 2 and on `its upward vstroke will dis# place air from within the cylinder, thus raising'the valve 16 from its=seat 10, allowing theexpelled air to pass into the distributingchamber or mixer 11, and as this .air passes the'face of the valve seat 10 the inlet openings in the supply tubes' 15 being uncovered 'by the lifted valve 16, there will be induced through the tubes 15 a supply of fuel which will be sprayed into the port 10 and sprayed upwardly by the upward inclination of they ends'ot the ducts in the head 9 againstvthe face of the valve 16, the atomizer fuel entering the chamber 2 through the open port or seat 10 and thus enriching the air Within the cylinder above the piston 3 when the 30 gling of the vapor particles with the air coni stituents,^and the tendency of the formation of the vacuum permitting themore rapid evaporation of the particles of the vapor and a subsequent expansion of the gas produced by the evaporation of thc vapor. Thereafter on the upward stroke of the piston 3 the expanded tvapor and enriched air will be compressed and expelled through the port or scat 10 against the valve 16 and across the faces of the ducts Aconnecting with the inlet f I tubes 15. U

As the enriched m1xture from the cylinder 2 passes into the mixing chamberor distributer 11 it is further mixed with an in- -stance at theengine 12.

necessary to snpplytheproper quantity and* quality 0f WPOI t0 the engine. The peedf of reciprocation' of the piston/3 may be` determined according to the size of the engine Aand the number of 'itsI cylinders so that there will be a substantially constant' supply ot' enriched vapor from/the into the mixing chamber 11. It is under- I stood that various modifications, alterations and. variations of the structure may begresorted to Within the limits of my present invention and within the scope of the appended claims.-

What is claimed as new is:

1. A carbureter comprising a vacuum pump having a port at the outer end of the cylinder for induction and eduction of air, an outwardly opening valve yieldingly seating over the port, and means for supplying liquid to the pump at said port to be mixed with the passing air.

2. A carbureter comprising a vacuum pump having, a port at the outer end of the cylinder for the inlet and outlet of air, means for supplying liquid fuel to the pump at the port, and a yielding valve controlling inlet and. outlet of air and liquid fuel through the port."

`3. A carbureter comprising adistributing ychamber having air inlet means, a vacuum pump having a sirgle inlet and outlet port leading to the chamber, an automatic outwardly opening valve for the port, and means for supplying liquid fuel to the pump, which liquid fuel is mixed with the expanded and compressed air and returned to the chamber.
